Today, Genentech released a statement (see below) regarding particulate matter found in Emicizumab. (HEMLIBRA) They noticed the matter back in March. It's now October. Even though this particulate matter found in Hemlibra is, this time around, non-life threatening, Genentech notified the FDA and other agencies BEFORE notifying the people injecting the drug.
Maybe Genentech wanted to keep this quiet for several months because adding this news on top of the recent fatalities report would impact sales?
What else are they holding back?
